Do PV systems need lightning protection?

With all the barriers discussed in Section 3.3, the need for lightning protection on PV systems must be evaluated on the basis of the risk analysis and protection costs. Table 10 presents the recommended standards related to PV systems including PV installations, lightning protection systems and electrical installations. Table 10.

Are PV systems vulnerable to lightning?

Similar to other power systems [ , , , , ], PV systems are vulnerable to lightning because they are always installed in unsheltered open areas. Recent studies on lightning protection of PV systems have drawn much attentions [ 9 ].

How do I protect my PV system from lightning?

Protecting the PV system Effective protection against partial lightning currents can be achieved through installation of Surge Protective Devices (SPDs), on both the DC and AC sides of the DC-AC inverter.

How vulnerable are photovoltaic systems to lightning strikes?

Photovoltaic systems are vulnerable to both direct and indirect lightning strikes. Therefore, they must be built with reliable and properly installed surge protection. (References: [1] Lightning Protection Guide, DIN EN Standard 62305-3, 2014. [2])

How will a lightning protection system affect PV power generation?

All this kind of destruction will undoubtedly affect the economic aspects or the return on investment that could be earned from PV power generation as well as the cost of repair or replacement to recover from the damage, all of which can be mitigated by implementing a lightning protection system (LPS) .
